IMPROVEMENT IN PAPER BOXES- Specification forming part of Letters Patent No. 193,932, dated August 7, 1877 application filed May 12,1877. I

To all whom it may concern: in Figs. 1 and 2. The dividing-lines 3 3 3 3, Be it known that I, GEORGE A. DENISON, which form theedges of the corner flaps and of Ghicopee, in the county of Hampden and end main flaps G G, are merely out through the state of Massachusetts, have invented certain stock without removing any great body of said new and useful Improvements in Paper Boxes stock, and'they are curved for the purpose of for a Bntter'Garrying Dish, of which the folgiving greater strength to the box, and also lowing is a specification: to make the outer edges of the lugs 00 slightly My invention consists of the peculiar conhooked, thus forming a better look.
